摘要
生物多样性的总经济价值包含了它的可利用价值（ｕｓｅｖａｌｕｅ，ＵＶ）和非利用价值（ｎｏｎｕｓｅｖａｌｕｅｓ，ＮＵＶ）。可利用价值可以被进一步分成直接利用价值（ｄｉｒｅｃｔｕｓｅｖａｌｕｅｓ，ＤＵＶ），间接利用价值（ｉｎｄｉｒｅｃｔｕｓｅｖａｌｕｅｓ，ＩＵＶ）和可选择价值（ｏｐｔｉｏｎｖａｌｕｅｓ，ＯＶ），即可能的利用价值。非利用价值主要是存在价值（ｅｘｉｓｔｅｎｃｅｖａｌｕｅｓ，ＥＶ）。生物多样性所提供的使用价值常常不能就地实现，而可能会通过某种通道，在空间上的流动，到达一个具备适当外部条件的地区，实现其使用价值。我们称这种现象为生物多样性价值在空间上的流动。
Conceptually, the total economic value of resource consists of its use value and nonuse value. Use value may be broken down further into the direct use value, the indirect use value and the option value (or potential use value). The realization ways of the use values of biodiversity are different because of the differences of useable ways. Some use values provided by biodiveristy cannot realize on the spot usually. These use values may transfer spatially by a certain of “passages' to attain to a spot where some suitable external condition are provided to realize them. That phenomenon is call as the “transfer of value of biological resource spatially”.
